This happens because some Internet Service Providers have aggressive spam filters that consider the protected document (.pdc file) as spam. If you don’t allow spam to come through then the email will be deleted.
Here are the instructions for a few internet providers, to allow spam through.
Log into your mail account
Select Options > mail > mail filters > spam
Make sure you’re allowing spam to go into spam folders and not on automatically delete.
The next protected document you receive will go into the spam folder. When this occurs, select the option ‘this is not spam’ and from now on they should start going into your regular mail program.

This is a 2 step process:
log into your email account
go to “settings” > junk mail > “filters”
you will have 4 options
pick the one that allows you to place emails in your junk mail. If you choose this, the email will show up in your spam folder even if you click “NOT SPAM”.
go to settings > options > allow or block messages
Select the allow tab and type the email address of the person sending it to you. This will allow it to go through.
Log into email account
click “email” tab
scroll down to “my settings” on right side
go to “spam filtering”
click “save spam” in spamdetector folder
GO BACK TO THE TOP OF THIS PAGE
there are 5 tabs (setup, signature, blocking, filters, pop)
Choose “blocking” tab
scroll down and go to “safe list”
when you reach “safe list” add the email address you receive the document from to the list.
Please keep in mind these are suggestions, if you are still having problems contact your email provider on how to allow this email, which can sometimes be considered spam.
